In summary

The ISNE international training course aims at promoting knowledge in the field of nuclear sciences. This module breaks down into two distinct parts: the "Thermal hydraulics of light water reactors (LWR)",
and "Modelling and multi-phase phenomenology of severe accidents in LWRs ".

This training course is accessible online, upon request.

Who should take this course ?

The doctoral course is designed for young researchers, PhD students, post-doctorates and engineers from nuclear industry companies, research centres, Universities, Technical Safety Organizations (TSO), regulatory bodies.

Learning outcomes

See the 2022 International School Brochure

  • Describe the various scales of two-phase flow modelling and their significance.
  • Present the different formulations of the 1D two-phase flow modelling (number and nature of balance equations, set of dependent variables, closure laws).
  • Give practical and relevant examples of thermal hydraulics models in the nuclear field.
  • Identify and to discuss the major physical phenomena involved during design basis accident and severe accidents.
  • Describe the different scenarios of core degradation and corium interactions during severe accidents.
  • Present the hydrogen risk in LWRs.
  • Technical visit organized (if possible, depending on the availability of the experimental facilities)
  • On-field experience, case study and tutorials
  • Lectures taught by international experts, including :

Dominique Bestion, Director of Research at CEA

He has been developing two-phase flow models for the CATHARE system code for 35 years, and has coordinated two-phase flow modelling in the NEPTUNE French multi-scale thermalhydraulics platform. He is chairman of the technical meetings of the FONESYS international network of code developers.

 

Florian Fichot, Expert at the Institut de Radioprotection et de Sûreté Nucléaire (IRSN)

He has been working for 25 years in the field of severe accidents. He contributed to the modelling of core degradation, thermal hydraulics and corium behaviour during the development of ICARE/CATHARE and ASTEC codes. He was coordinator of the IVMR European project (2015-2020). 

 

Etienne Studer, CEA International Expert in fluid mechanics and hydrogen risk issues

He has 30 years of experience working in the field of hydrogen risk in nuclear power plants, and has participated to international experimental programs, international working groups and state-of-the-art reports. He takes part to the “European Hydrogen Safety Panel”.
